Elections supervisors Friday said they had certified 710,508 signatures, more than the 683,149 needed to get on the ballot.

Gov. Rick Scott has said he will vote against a proposed constitutional amendment to allow the medical use of marijuana if it makes the 2014 ballot.

Scott said through a spokeswoman Tuesday that he has empathy for people battling difficult diseases, but he's also seen the damage drug abuse can do. Scott previously has said he is opposed to "illegal drug abuse" and he's supported Attorney General Pam Bondi's challenge to keep the proposal off the ballot.

However, he's been less specific about the medical marijuana issue.

Scott's Democratic challengers, former Gov. Charlie Crist and state Sen. Nan Rich, have said they'll support it.
